Tesselation creates an illusion that theres more polygons on a rendered object than there actually is. So yeah

False, tesselation actually changes the number of polygons in a model.

What you are thinking of is bump mapping (and normal mapping, parallax etc) which use texture effects to create the illusion of greater model complexity.

it works best on flat surfaces, and doesn't change the actual geometry and silhouette like tesselation does.
